Member Function Documentation

void Transformable::init

(

)

[virtual]

Initializes this Transformable's world-space AABB, assuming a derived class has already filled in m_objSpaceAABB.

Reimplemented from Shape.

Reimplemented in Blob, Implicit, InstancedShape, Mesh, Plane, PointShape, ShapeSet, and Triangle.

Definition at line 28 of file Transformable.cpp.

void Transformable::preview

(

)

[virtual]

Display a crude OpenGL preview of this shape

Note:

Default implementation sets the ModelView matrix appropriately with respect to this Transformable's transformation

Reimplemented from Shape.

Reimplemented in Blob, Cone, Cube, Cylinder, InstancedShape, Mesh, Plane, PointShape, ShapeSet, Sphere, and Triangle.

Definition at line 15 of file Transformable.cpp.

Point3 Transformable::getPosition

(

const UV &

uv

)

[virtual]

Note:

implementation returns the origin of this shape in world space because not all shapes support this functionality

Reimplemented from Shape.

Reimplemented in InstancedShape, Mesh, Plane, Sphere, and Triangle.

virtual bool Transformable::isTransformable

(

)

const [inline, virtual]

Returns:

true iff this Shape subclasses Transformable
